This invention relates to a new and improved bobbin.

In the manufacture of thread such as silli, cotton, rayon, etc. and atsubsequent times 1t 6 is usual for-convenience in handling, storing,knitting, etc. to wind the thread upon a bobbin from which it isthereafter unwound or rewound into skeins or other forms for futureprocessing and repeated winding and rewinding of the thread, is not onlyundesirable from the standpoint of breaking or injuring the thread, butit is also expensive, and the main object of this invention is theprovision of a bobbin of such form and construction that thread can beefficiently and uniformly processed upon the bobbin itself for anypurpose such as washing, de-sulphurizlng, bleaching, 1 etc.

Other objects and advantages relate to the details of construction ofthe bobbin and the form and disposition of parts thereof, all as willmore fully appear from the following description taken in connectionwith the accompanying drawings, in which:

Figure 1 is a perspective'view of the preferred form of my device.

Figure 2 is a section on line 2 -2 of Figure 1.

Figure 3 is a section similar to Figure 2 of a modified form of bobbinwith a plug in the end thereof.

Figure 4 is a section on. line 4-4, Figure 1. Figure 5 is a viewpartially broken away of a modified form of the invention. 5 Figure 6 isa section on line 6-6, Figure 5. igure 7 is a section on line 77, Figure6. The bobbin 1, as shown, is cylindrical in shape although certainobjects of the invention may be obtained with variously shaped bobbins.Further, as shown in Figures 1 and 2, the bobbin may be formed with aclosed end --2-, although that is not essential, as the bobbin may beopen at both ends and during p1 ocessing of thread thereon, one end ofthe bobbin may be closed by a removable plug 14. As shown in Figure 3,the bobbin may be formed of any suitable material, but at present Iprefer one made of fibre.

The wall of the bobbin 1 is formed, as

shown, with a plurality of perforations 4 in circumferential s acedrelation and also spaced, as shown, f i'om the end 2 of the bobbin.Another plurality or row of perforations 5 is provided in the bobbin incircumferential spaced relation and spaced from the end 3 of the bobbinsubstantially as shown. The intermediate portion of the wall of thebobbin between the rows, 4. and 5, of perforations is provided with amultiplicity of uniformly spaced perforations. These perforations 6 may,as shown, be arranged in rows extending around the bobbin, or may bestaggered, or otherwise arranged so long as they are substantiallyuniformly spaced to provide uniform capacity for transmission of fluidfrom the interior of the bobbin to yarn or thread wound thereon.

The usual method of winding thread upon a bobbin involves a traversingmovement of the thread guide combined with a relative longitudinalmovement of either the thread guide or the article or bobbin upon whichthe thread is to be wound, with the result that the material or threadwound on the central portion of the bobbin is of substantially uniformdesired depth and tapers off at opposite ends of the central, unlformlythick, portion toward the opposite ends of the bobbin, as for instance,illustrated in dotted lines in Fig. 2. It will be apparent that ifthread so wound upon a bobbin is to be treated by fluid passing throughthe perforations in the bobbin that a gradually decreasing quantity ofsuch fluid is required to effect treatment of the thread at the opositely tapered end portions of the b0 y of the thread wound upon thebobbin. For

that reason, the opposite end portions of the bobbin including a spaceunderlying at least a considerable portion of the tapered ends of thecop of thread are unperforated and in order to supply the desiredquantity of fluid to the overlying portion of the thread or yarn, theseopposite end portions of the bobbin are provided with a plurality ofgrooves 7 leading from perforations in the opposite end rows 4 and 5 andextendin toward the ends 2 and 3 respectively, suc

grooves-or channels gradually diminishing in depth as they approach theends 2 and 3 respectively until they become flush with and blend intothe outside surface of the bobbin at the points where the layer of yarnor thread upon the bobbin terminates. In this manner, fluid isdistributed in gradually decreasing amounts to the opposite tapered endportions of the body of thread or cop wound upon the bobbin, in otherwords, the amount of fluid supplied to the intermediate, uniformlythick, portion of the cop is greater than the amount supplied to thetrated in Figure 3, this permanently closed wall may be omitted and thebobbin may be formed with both ends open, but adapted to be closed inany suitable manner during processing as by a movable plug 14.

Although it is not essential, under some conditions, it may be desirableto connect series of openings or perforations through the bobbin wall. Ihave illustrated in Figure 1 two such channels 13 extending lengthwiseof the bobbin and connecting a multiplicity of perforations to assist inuniform distribution of fluid. These channels, however, may extendeither circumferentially or longitudinally, or in both or otherdirections with respect to the bobbin.

In Figs. 5, 6 and 7 a modified form of struc-' ture is illustrated, butwhich by reason of its formation is adapted for the supply ofsubstantially uniform quantities of treating fluid to thread wound uponthe bobbin, as

for instance in the form shown in Figure 2. This modified form of theinvention includes theend rows of perforations 4 and. -5 respectivelyand the multiplicity of intermediate perforations 6-, but instead of thegrooves or channels -7- the opposite end portions of the bobbin areformed with ribs 20 which taper outwardly toward the opposite ends ofthe bobbin from a pointadj acent the opposite end rows of perforatlons4:- and --5 respectively, i. e. at the end rows of perforations the ribsare of a height suflicient to space the yarn wound thereon a shortdistance from the periphery of the bobbin, and from that point the ribsgradually decrease in height until they merge into the surface of thebobbin at substantially the point where thewound yarn terminates so thatthe spacing of the yarn from the bobbin gradually decreases in extent asthe layer of yarn wound upon the bobbin gradually decreases inthickness.

Except as to the substitution of ribs -20 for channels 7 theconstruction shown in the several figures is the same.

It will be understood that the size, number and position of theperforationsin the central portion of bobbin, 1 may bevaried, dependingupon the thicknessof the cop and the material of which it is formed.This is also true of the grooves 7 and -8. 01'.

the ribs 20 which may be varied in mun: her, size and depth, dependingupon the thickness and character of the material to which fluid is to besupplied.

It will also be understood that the size and shape of the bobbin itselfmay be varied, as may be the material of which it is made, for althoughI have shown and described a specific structure and form of parts, as anexemplification or embodiment of my invention, I do not desire torestrict myself to the exact size, shape or relation of parts thereof,as various changes may be made within the scope of the appended claims.

I claim:

1. In a device of the class described, a hollow body having a pluralityof perforations in the periphery of the central portion thereof and aplurality of grooves in each end portion of the body, each grooveextending from a point adjacent an end of the body towards and intocommunication with a perforation and gradually increasing in depth as itapproaches such perforation.

2. In a device of the class described, a hollow body having a pluralityof perforations in the body in spaced relation extendingcircumferentially and longitudinally of the central portion and having.a' plurality of grooves extending from certain of said perforationstowards one end of the body and having a plurality of grooves extendingfrom certain others of the said perforations towards the other end ofthe body, said grooves gradually decreasing in depth as they approach anend of the body.

3. In a device of the class described, a hollow body having a pluralityof apertures in the periphery of the central portionthereof and having aplurality of grooves connecting adjacent perforations and a plurality ofgrooves in each end portion of the body, each groove extending from apoint adjacent an end of the body towards and into communication with a'perforation and gradually increasing in depth as it approaches suchperforation.

4. In a device of the class described, a bobbin body having a pluralityof apertures in the periphery of the central portion thereof, and aplurality of grooves in each end portion thereof, each groove extendingfrom a point adjacent an end of the body toward and into communicationwith a perforation and gradually increasing in cross-sectional area asit approaches such perforation.

5. In a bobbin adapted to have wound thereon thread in a layer ofnon-uniform thickness, a hollow body adapted to receive a treating fluidtherein, said bod having means for 5 conveying treating fluid rom theinterior of the body to the outside surface thereof in varyingquantities including grooves varying in capacity from end to end, suchquantitles being proportional to the thickness of the layer of thread atthe point of supply thereof.

In witness whereof I' have hereunto set my hand this 7th day ofDecember, 1928..
